Ask HN: Have you ever freight shipped furniture internationally?

I have some old family belongings and furniture I would like to ship from central/eastern Europe to the States. I have seen a few websites that require contact forms, quotes, consultations, etc. My question is: has anyone had success shipping items like this? How do you find a service? What approximate costs can I expect?

I don't need speed nor is this a "relocation" type of shipping.
